Iggy Azalea & Kesha Ridin' Hard For Each Other

040716-iggy-azalea-kesha-twitterIggy Azalea's got a new riding partner who's also trying to buck a slew of personal drama -- Kesha's now saddling up with the rapper.

Kesha turned up in the corral next to Iggy ... trying her hand at some equestrian therapy. 

The duo look like they're trying to present a united front in the pic, which Iggy posted. More proof these chicks ain't playing -- their horses are named Biz and Defender.
